IPC: C08L25/18
Filed: 1985-09-17
Abstract: PURPOSE:To provide a resin compsn. having excellent flame retardance and moldability and good physical properties, by adding a flame retarder and a specified flame-retardant aid to a mixture of a thermoplastic polyester and a polycarbonate. CONSTITUTION:A flame-retardant resin compsn. is obtd. by adding a flame retarder (A) composed of an org. halogen compd. (e.g., a brominated polystyrene) and a flame-retardant aid (B) composed of an Sb compd. obtd. by heat-treating a compd. of the formula (wherein X is 0.1-0.8; Y is 0.25-4.0) at 100 deg.C or higher to a mixture of a thermoplastic polyester (C) (e.g., polyethylene terephthalate) and a polycarbonate (D) (e.g., bisphenol A). The use of the flame retarder (A) together with Sb2O3 as a flame-retardant aid to impart flame retardance has a disadvantage that it causes foaming.

Title: Device for switching placed between two film holders
Inventor: FURUKAWA KUNIYUKI
IPC: G03B19/06
Filed: 1981-12-18
Abstract: PURPOSE:To switch an optical path by a simple constitution, by constituting so that a light shielding plate provided so as to be insertable and detachable between a reflector and each film holder is inserted and detached by interlocking with the reflector. CONSTITUTION:When a self-processing type film (fitted to a mount 2) is selected as a photographic film by fitting a film holder to each film holder fitting mount 2, 3, and thereafter, placing a reflector 4 on an optical path from an objective lens 0 by pushing in a sliding lever 5b, a light shielding plate 6 is detached from the optical path and is inserted between the reflector 4 and the holder fitting mount 3 for a 35mm. film. When the lever 5b is drawn out and the reflector 4 is detached from the optical path, the light shielding plate 6 gradually starts to be inserted into the optical path, and immediately before the reflector 4 is detached completely from the optical path, the light shielding plate 6 intercepts light between the reflector 4 and the mount 2. When the reflector 4 has been detached completely from the optical path, the shielding plate 9 is detached from the optical path instantaneously through a spring. In this way, the optical path can be switched by a simple constitution.

Inventor: YASUMURA MASAYUKI
IPC: H02M3/28
Filed: 1985-09-14
Abstract: PURPOSE:To decrease the number of expensive voltage dividing resistors for high voltage, to reduce power consumption, and thereby to cut down cost by stabilizing the output voltage from the secondary of a power source transformer and connecting an excess voltage protection circuit and a high voltage detecting- shortcircuiting-protecting circuit commonly to the voltage-dividing output terminal of the voltage dividing resistor for high voltage. CONSTITUTION:When the voltage dividing output terminal of the voltage dividing resistor 16R is released, a circuit power-source current flows from the common emitter resistor 18g of the differential amplifier of the excess voltage protection circuit 18 to the base of the transistor Tr 16a of a control circuit 16 via the emitter-base of a Tr 18a. And the Tr 16a turns on, causing a Tr 16d to be on, and the high output voltage HV drops. Accordingly, when shortcircuiting a load or releasing, damages, breakage, etc. of high voltage diodes DH1 and DH2, high voltage capacitors CH1 and CH2, cathode ray tube 20 and other components due to a high voltage exceeding their insulations can be prevented from occurring by the high voltage detecting-shortcircuiting- protecting circuit 19.

Filed: 1983-10-31
Abstract: PURPOSE:To provide the interchangeability of a magnetic disc between one side face magnetic disc recording devices by always recording/reproducing signals at one side magnetic head only when the magnetic disc is inserted in a direction opposite to the normal direction. CONSTITUTION:When an inserting direction detecting mechanism detects that a magnetic disc 1 is loaded in opposite direction, a drive signal is transmitted to predetermined recording/reproducing heads 16a, 16b independently of a side selection signal via a selection logical circuit. In recording a data to both A and B sides of the disc 1 to be reproduced from a one side magnetic disc recording device by using a both side magnetic disc recording device, for example, the disc 1 is loaded at first in the normal direction, the data is recorded on the side A by the head 16a of the side 0 and the data is recorded on the side B by the head 16a of the side 0 similarly while loading the disc in the opposite direction. Thus, the interchangeability of the magnetic disc with the one side face magnetic disc recording device is provided.

Title: Mask rom
Inventor: HONMA TAKESHI
IPC: H01L27/112
Filed: 1991-08-14
Abstract: PURPOSE:To limit leakage currents through a bit line to a small value by a select transistor when data from a memory transistor are read by making the gate length of the select transistor longer than that of the memory transistor. CONSTITUTION:When both a select transistor Q31 and a memory transistor Q21 are depleted, charges are discharged to a ground GND through select transistors Q31, Q32 and memory transistors Q21-28 from a bit line BL. However, the gate length of the select transistor Q31 is made longer than that of the memory transistor Q21. Consequently, the magnitude of currents made to flow through the GND is limited at a value smaller than a conventional device by the select transistor Q31. Accordingly, a potential drop is difficult to be generated by leakage currents in the bit line BL, and data from the memory transistor are read under the state stabler than the conventional device.
